非工作时间电子沟通对领导有效性的影响: 一项经验取样的日志研究

文章基于社会信息加工理论,从领导有效性和下属工作态度两个角度探索非工作时间电子沟通在工作领域的有效性及其影响机制。使用日志法追踪员工10个工作日获取613份有效观测值,数据分析发现：非工作时间电子沟通的情感基调维度通过任务不合规性感知积极影响领导有效性评价和员工总体工作态度;而所需时间维度通过任务不合规性感知对领导有效性评价和员工总体工作态度均有消极影响,工作—家庭细分偏好加强了非工作时间电子沟通与任务不合规性感知之间的关系。研究还讨论了理论和实际意义以及未来研究的方向。     

Electronic Meetings and Intense Group Conflict: Effects of a Policy-Modeling Performance Support System and an Audio Communication Support System on Satisfaction and Agreement

Ad-hoc decision teams were used to examine the effects of an electronic meeting system (EMS) on group satisfaction and agreement. The decision task provoked intense conflict of values. The EMS had two core features - a policy-modeling group performance support system (incorporating structured decision methods and computer-supported cognitive feedback using Multi-Attribute Utility Analysis and Social Judgment Analysis), and an audio-based group communication support system (allowed dispersed members to communicate by voice). Policy groups reached higher agreement than conventional decision-making groups, apparently due primarily to the structure for cognitive-conflict tasks that was imposed on group discussion rather than computer-supported cognitive feedback displays. Audio groups were more satisfied with the conflict process than face-to-face groups. Decision agreement was equivalent across the two media. These audio effects for a highly equivocal task represent a further challenge to media richness theory.
